DAIRY ANIMAL RESTRAIENING ARM Filed Oct. 3, 194-2 INV N TOR. /%awchions in Patented 31, 1 943 7 f a Andre This invention relates to cow stalls" the dairy-animal in a clean condition. Lil f It is-a commonly known iactamong dairymen that most animals habitually humpf their backs and move forward 'when evacuating'i for ward movement brings the animal -into such a position marine evacuation usually-{falls on the: customary stall platforms instead of into the gut-1" ter and consequently soils thebedding an 'c'zai ses the stall to become unsanitary andmesses up tl ne cow, especially its udder;

Now it' has been known that if a restraining bar is properly a adjusted s ove the egw's back,-

near the shoulders f she cannot: her back: until she first backs fromunder it far" enough {to secure freedon fr'om therestraint; 'li'l iis compels the animal to be near: enough 3 to the: gutter =so= that the discharge falls therein instead off than the platform ahdbedding.) As a result the platis kept clean.

A number of devices have been made for accomplishing the above purposes but such devices have been deficient in various respects and have not been entirely satisfactory. For example,lthe prior devices are expensive to make or maintain or are too complicated in their application.

One object of my invention is to provide an improved and greatly simplified device that is. rugged and yet flexible in its application to existing stanchion equipment and maybe constructed and installed in a relatively inexpensive manner so that the device will be within the reach of all dairymen but'without in: any waysacrificing the desirable functions ofsuch equipment.

Furthermore, theease' with which my improved construction permits the device to be adjustedto different, heights of animals increases. the probe l bility" that such adjustment; when required; will.

The value of these features is more readily appreciated whenit is considered that certain types or stanchionsl-l-or yokes'can be adjusted'so I asjto plac theparticular 'animalin it's stall at a" point thatievac'uation" will fallin the g'u'ttei'J However when this 'is" done,- the yoke ofttimes chafes iand; engenders sores on the neck of i the 3 animal when' it reach'es forwardfor its fodder; I

T

A more specific object is to provide an improved device that is easily attached to metal stallsand stanchions and is readily adjustable to all sizes of dairyanimals. '1 w r i a v 7 My invention is as nearly fool proof as possible in that its peculiar simplicity of design permits in itself so simple a to be conducive to maxi V mum sanitation oi the equipment'as well as being the use of a preferably tubular construction that is sufliciently rigid to resist bending and yet allows the use of' a relatively simple clam-ping ar rangement that lends sumcient flexibility and v yielding of the device to upward pressure exerted the T, it being noted in Fig. 3 that thi head 2, and a top'rail 3, this; top rail being supported: by vertical fixed standards] to which are attached the stall partition rails (not shown for purposes of clarity). Suspended from the center of the top rail 3 is'onelwell known type of flexible stanchion 5, which isheld in 'position by a usual clamp. 5",.Fig. 3, secured to thetop rail. Within the stanchion the animals head is secured, but. with freedom of movement, which will allow the animal to lie down as well as" have somewhat restricted movement forward and backward in the stall.

My invention contemplates the use of an extremely simple T shaped restraining arm,generally indicated at 6 and specifically consisting of a main stem having two angularly related p01"- tions 6" and Lthe portion 6' preferably'being substantially horizontal andthe portion "I being inclineddownwa'rdly; Secured. to the inclined portionfl is a substantially horizontal head 8 of 8 is of unequal length on opposite sides of the stem i. This inequality accomplishes the functionof permitting the arm 6 to be clamped to the I top rail 3' at a point slightly offset from the stanchion clamp 5' while still allowing the ends of the T head to be transversely symmetrical with respect to the stall and animal.

The foregoing offset support of the T stem on the top rail 3 permits the use of a simple direct I clamping device consisting of anadapter member 9, preferably madeof wood, having a fiat upper surface In and a semi-cylindrical recess II to re lceive top rail 3. A U shaped bolt I2 passes around the rail 3 and through both the block 9 and holes in the horizontal stem portion ;6-. The" U bolt when tightened, firmly clamps the restraining arm in position although my improved arrangement" allows the arm to be readily angularly adjusted on.

the cylindrical surface of the top rail 3 merely by slightly loosening the nuts of the U bolt.

My. improvedvfls arm, arrangement is: not only simple, rugged and direct imitsxoperationand construction but also by ViIfillefif; the single stem dinal adjustment merely by providing any desired number of, U bolt 11018513 extending through the stem portion 6?. Avfurther advantage is that the stem 6 and its head 8 may bemade, in aninex I pensivemanner, of. pipe or oth rtubu1 1material welde'dtogether at; the juncture o fithe' head and stem.; l y a In Fig. 4 theT stem 6 and block 9 are posiwhile the animal is held in stantioned on the under side of the top rail 3. This is accomplished by merely using the parts previously described but inverting the same. When this is done the arm 6 is rotated 180 about its axis in relation to block 9. c

'It will be seen from the drawing and description that I have provided a device that is extremely simple in design, of few parts, readily adjustable and economical both as to amount and cost of material and the labor to manufacture and install the device, all of this being in addition to the Very desirable function that the single T arm stem'allows maximum accessibility around the animals neck and head when occasion requiresitQ Z I The invention is define-d in the following claims.
